### Standards:
1. Next Generation Science Standards (NGSS): 4-PS3-4, 4-LS1-1
2. Common Core State Standards (CCSS) for English Language Arts: ELA-Literacy.W.4.2, ELA-Literacy.SL.4.1
### Lesson Sequence:
#### Introduction (10 minutes):
1. **Engage**: Begin with a question to spark curiosity. "Have you ever wondered how scientists learn about the world around us?"
2. **Discuss**: Explain that scientists use a special process called the scientific method to investigate questions and discover answers.
3. **Vocabulary Introduction**: Write the key vocabulary words on the board. Briefly define each term with the class.
#### Direct Instruction (15 minutes):
1. **Explain the Scientific Method**:
- **Ask a Question**: The inquiry begins with a question about something observed.
- **Do Background Research**: Gather information and resources.
- **Construct a Hypothesis**: Formulate an educated guess.
- **Test with an Experiment**: Design a way to test the hypothesis.
- **Analyze Data and Draw a Conclusion**: Look at the results and determine if the hypothesis was correct.
- **Communicate Results**: Share findings with others.
2. **Modeling**: Demonstrate a simple experiment—show how to ask a question, develop a hypothesis, and test it using an example (e.g., "Will a balloon inflate if we mix baking soda and vinegar inside a bottle?").
#### Guided Practice (15 minutes):
1. **Group Activity**:
- Divide students into small groups.
- Provide each group with experiment materials.
- Instruct each group to choose a question and write a hypothesis.
- Guide them through designing a simple experiment to test their hypothesis.
2. **Conduct the Experiment**:
- Encourage students to wear safety goggles.
- Have them conduct the experiment, making careful observations and recording data in their science journals.
#### Independent Practice (10 minutes):
1. **Data Analysis and Conclusion**:
- Ask each group to analyze their data and draw a conclusion based on their observations.
- Provide data recording sheets to help structure their findings.
2. **Share Results**:
- Each group presents their experiment, findings, and conclusions to the class.
#### Closing (10 minutes):
1. **Reflection**: Lead a class discussion about what was learned and different group results.
2. **Q&A**: Allow students to ask questions about what they did and observed.
3. **Application**: Challenge students to think of other questions they could investigate and how they might do so.
### Homework:
- Assign students to choose a simple question they can test at home using the scientific method and to bring their observations and conclusions to share in the next class.
### Assessment:
- **Formative**: Observe student participation and understanding during group activities.
- **Summative**: Evaluate the students' science journals and data recording sheets for completeness and understanding.
### Extensions:
- **Advanced Students**: Have students design more complex experiments and research background information in more detail.
- **Struggling Students**: Provide additional support by pairing them with a peer or providing more guided step-by-step instructions.
### Resources:
- Books on basic science experiments for kids.
- Online videos demonstrating simple science experiments.
- Educational science websites for kids.
### Notes:
- Ensure safety throughout the experiment, especially when handling materials like baking soda and vinegar.
- Encourage collaboration and respect during group activities.
This lesson plan offers a hands-on approach to understanding scientific investigation and experimentation, which encourages curiosity and critical thinking in young scientists.
